Within the German federal government regular staff rotation is a precautionary measure against corruption in public administration. To study the effect of this policy, an experiment was conducted where pairs of potential bribers & public officials were randomly re-matched in every round. The outcome is compared to the case where the identity of the pairs interacting remained fixed. The conclusion is that rotation of interacting pairs significantly reduces the levels of bribes as well as the frequency of inefficient decisions due to bribery. 6 Figures, 2 Appendixes, 33 References.

We study in-group favouritism and out-group discrimination in a multiplayer dictator game in a naturally occuring group setting. An allocator divides a large sum of money among three groups of around 20 recipients each and also to themselves. The groups are supporters of two rival political movements in Thailand and politically neutral subjects. The non-rival outgroup acts as a reference point and allows us to measure in-group favouritism and outgroup discrimination. A treatment with artificial groups serves as a control. We find both ingroup favouritism and out-group discrimination among the naturally occurring groups. In artificial groups, favouritism is observed, but not discrimination. Our results suggest that the two behaviours are not driven by the same motive, and only when groups are in conflict that out-group discrimination is likely to occur.

We use a game-theoretical model and results from laboratory experiments to study the process by which subordinated regions of a country can obtain a more favorable political status. In our theoretical model a dominant and a dominated region first interact through a political process. This process involves two referenda, one at the level of the country as a whole and one at the level of the subordinated region. If the political process succeeds, then the new autonomy level is implemented. If this process fails, then both regions engage in a costly political conflict in which both sides can spend resources to win the upper hand. We show that in the subgame-perfect equilibrium of our game the voting process leads to an intermediate arrangement acceptable for both parts so that the costly political struggle never occurs. In contrast, in our experiments we observe frequent fighting involving high material losses.

We study the process by which subordinated regions of a country can obtain a more favourable political status. In our theoretical model a dominant and a dominated region first interact through a voting process that can lead to different degrees of autonomy. If this process fails then both regions engage in a costly political conflict which can only lead to the maintenance of the initial subordination of the region in question or to its complete independence. In the subgame-perfect equilibrium the voting process always leads to an intermediate arrangement acceptable for both parts. Hence, the costly political struggle never occurs. In contrast, in our experiments we observe a large amount of fighting involving high material losses, even in a case in which the possibilities for an arrangement without conflict are very salient. In our experimental environment intermediate solutions are feasible and stable, but purely emotional elements prevent them from being reached. ; Financial support from the Spanish Ministerio de Ciencia y Tecnologia (BEC 2003-00412), the Ministerio de Educación y Cultura (SEJ2005-01690), the Barcelona Economics program of CREA, the British Academy and the University of Nottingham is gratefully acknowledged.
